I reckon an idea for next year is instead of Away jerseys of current players, do heritage players.
Alexander or Simmons in the chocolate soldier or 1991 licorice all sort; ET in Cronulla; Wally Lewis in the Gold Coast Seagulls; Langer in the 1992/93 jersey; Raudonikis in Wests or Newtown (or both!); Toovey in a Pepsi Manly.
And why stop there? It is obvious kids AND adults are collecting these things.
Why not do mini-sets you buy direct from the company with 5-6 players in a retro/heritage pack? So Souths 1967-1971 - McCarthy, Coote, Simms, Sattler and O'Neill; or Para 1981-1986 - Grothe, Sterling, Kenny, Price, Cronin, Ella; or Broncos 1992-1995 - Langer, Walters, Lazarus, Renoulf, Hancock; or Canberra 1989-1994 - Stuart, Meninga, Daley, Belcher and S Walters? The North Sydney Bears - Taylor, Florimo, Moore, Fairleigh and Larson; Manly circa 1993-1997 with Lyons, Toovey, Menzies, Carroll and Gillespie; Dogs mid-80s with Tunks, S Mortimer, Gillespie, Langmack.
They could do it with Men of League with some of the money going to the charity.
It would be awesome to buy sets of retro players. Hell, I'd buy a folder full of 'em.
And they should do team binders so you can keep adding your team players in.
There is limitless possibility with these figs. I can't see them going out of date or out of fashion. And new players come along all the time. Plus there are Dally Ms, SoO, Kangaroo/Kiwi rep figs (even Tonga, Samoa, etc), Immortals, Club Legends.
